Race For You difficulty
4.2/ 10
Moderate
Moderate evidence confidence · 56% evidence coverage
This score is driven most by balanced overall demands. Difficulty V2's separate time-limit modifier adds 0.35 points here and is capped at 0.70; a broad limit cannot erase extreme intrinsic demand. This is independent of the public Cutoff Pressure V2 band.
Weather, conditions and individual preparation can change the real difficulty significantly.

Course analysis
What shapes this race
Expect sustained upland ground and meaningful climbing, exposed moorland where weather can amplify the difficulty.

Climbing density
36.6m per km
A more useful comparison than total ascent alone: it shows how consistently the course asks you to climb.
Cutoff analysis
High pressure
To finish inside 10h, the raw average required is 12:00 per kilometre (19:17 per mile), including every stop.
Raw pace12:00/km
PressureHigh pressure
Cutoff pressure compares the published time limit with distance, ascent and verified course demands. Lower pressure does not mean the race is easy. Raw pace includes checkpoints, food stops, navigation errors and any sleep; it is not a pacing plan.

Data PartialThe organiser confirms 5 June 2027, 50km, nearly 6,000ft, ten hours and £56.50. Its current checkpoint lists conflict between 11/23.8/39km and 11/22/40km; they are retained as a source conflict rather than silently reconciled.
